Where is the key?

In a previous game, I received a (iron?) key when I killed one of the cyclops on Cyclops Coast. Unfortunately, I didn't save before I got killed, and so lost the key. Now I have completely cleared out Cyclops Coast, including the cave at the northern end, but no key. Did I do something wrong? I'm figuring this key may unlock the crypt I found up north recently (don't tell me...), but now I'm stumped as to how to get it again. Help!

the key is nothing special, also it wont show in your item list, its for opening the chests around the cyclops camp, you auto get it after killing all ten of them.
